In the Independence Party primary, Democratic District Attorney Richard J. McNally faces Republican challenger Joel E. Abelove. McNally also has the Working Families line, while Abelove has the Conservative.

No matter who wins the primaries, the candidates will face each other again in the Nov. 8 general election.

In North Greenbush, Charles B. Smith and Councilman Alson J. Spain Jr. oppose each other. Spain also has the Conservative, Independence and Republican lines. There is a Working Families opportunity-to-ballot to permit that party's voters to write-in a candidate for supervisor.
